Use a soldering iron and solder wick to desolder the four motors from the control board.

If the connection holds even after removing the solder from the joint, gently pull up on the wire while applying heat to the joint until the wire separates from the PCB.

The motor wires are in either black-white or red-blue pairs.

CAUTION: Overheating the PCB can damage the traces, making it difficult or impossible to reconnect the components later on. Do not apply too much heat to the board; these traces are especially delicate due to their small size.

Both the motor mounts and motors themselves have a small size variance. If it's difficult to push a motor out, ensure the wires are not caught on the frame and gently apply more force from the bottom until the motor begins to slide.

Once the motor is mostly out of the motor mount, grip it from the top and pull it straight out.

Unlike the motors which had colored wiring to differentiate between CW and CCW spin, both the blue and red LEDs have a red positive leads and a bronze negative lead. Upon closer inspection, it looks like the heat shrink on the postive lead matches the LED color.
